UL-certified control stations for
extreme temperatures
Cowan Dynamics
This company has obtained updated
UL approval for its explosion-protected
Ex e (increased safety) control stations
from the 8146 and 8150 Series (photo),
as well as its ConSig 8040 range of
control and signaling stations for use
in an extended ambient temperature
range. This means that 8146/55 Series
control stations are now suitable
for use across North America in hazardous
(classified) locations at ambient
temperatures between -50°C (-58°F)
and 40°C (104°F). The 8150/5 Series
of control stations, which is made out
of stainless steel, has been approved
for temperatures as low as -60°C
(-76°F) and up to 85°C (185°F). The
robust enclosures, which are available
in different dimensions, can be individually
configured and equipped with
control devices, indicator lamps, illuminated
pushbuttons, control switches,
ammeters and voltmeters. - R. Stahl,

Introducing a new range of
valve actuators
Launched in March, the E2HR Series
Electro-Hydraulic
applications.
Rotary
All
valve
actuators
(photo) feature a very small
installation envelope for ¼-turn valveactuating
hydraulic
components
and sensors are integrated
into a single compact manifold
block that also houses the actuator
and integral oil reservoir. The control
panel can be mounted directly to the
manifold block or installed remotely to
run multiple units from a single control
panel.
This
self-contained
actuator
can be installed either vertically or horizontally
and has no external piping. It
is available for on/off or modulating
applications and for a wide range of
markets and valve applications. The
valves' operating-temperature range
is -50 to 40°C, and they offer very low
power consumption and tight shutoff.
